<em>Note: It seems you have asked the exact same type of questions again and again. So, I will solve the first question. The rest of the questions is the carbon copy of the same concept and solution method. Hopefully, it would get your concept clear.</em>
Answer:
The distance between the points (3, 6) and (8, -1)
Step-by-step explanation:
Given the points
Finding the distance between the points (3, 6) and (8, -1)
(x₁, y₁) = (3, 6)
(x₂, y₂) = (8, -1)
Thus, the distance between the points (3, 6) and (8, -1)
NOTE: All the remaning questions have the same method of solution.
Answer:
I think the answer is going to be 14 or 21
I can give you an example:
4x^2+2xy-3y^2
it is in the form of :
x^2+2ax+a^2
also : (x+a)^2 = x^2+2ax+a^2
Surface area is the sum of all the areas of all the shapes that covers the surface of the object.
Surface area of a cube = 6 * a²
(a is the length of the side of each edge of the cube)
Surface area of a rectangular prism = 2ab + 2bc + 2ac
a = length
b = height
c = width
Answer:
<em>Colin spends 1/8 of an hour practicing each song</em>
Step-by-step explanation:
Colin's piano lesson is 3/4 of an hour, long.
In that period, he practices 6 different songs, spending an equal amount of time on each one.
This means that each song gets the sixth part of the lesson duration. The fraction that expresses that amount is:
Colin spends 1/8 of an hour practicing each song
